Hi, well I've get my Greddy SP2 cat back system fitted and wow! it's put the sports back into sports car. I highly recommend the system the sound is fantastic! and the HUGE pipes realy look the part to.
Though it is a much travelled system as manufactured in Japan, then shipped to the States then finally shipped to the UK.
Thanks Bob for your info which helped me select the system.

Well i am waiting this week the sp2 and i really don't know what to do..I have seen and heard the new Trust Titanium catback and really loved it and its weight is only 5kg...What is the weight of the sp2???

thank you GREATLY for the exhaust summary, it really helped me see that there was more than just the GReddy exhaust system for the rx-8. i have a question because i didn't see anything about the MAZDASPEED exhaust. is that one bad? or just dont have any information on it? i was considering buying the MAZDASPEED exhaust, but a lot of people dont mention it at all xP just wondering :]

^^^ its not worth the money.. go with cheaper or custom.. in addition i think the mazda speed sounds the closest to stock and dont look that great either...butthat my opinion.

I had no info on the MS exhaust when I put this list together.
General opinion is that the stock system is about as good as it gets for a system with cats.
Just go with what sounds good to you.

what was decided about the midpipe vs catback... i understand using both will be very loud but would it be worth it to use one or the other.. if so, which one, mid pipe or catback? Does the midpipe throw the CEL?

i am hoping that the exhaust system mentioned here and midpipes are C.A.R.B legal or smog legal in NJ...since i don't live in california, which is a shame, the stricter exhaust demands don't apply to me.

I just installed my Magnaflow exhaust and have to say, it sounds incredible and looks so much better than factory. As for power, maybe, it feels a little smoother from about 5k up, but i dont want to say until the newness wears off. Ill have dyno #s posted soon.

What about teh MS Exhaust?

I must say... that Hymee exhaust is beautiful

If only I could get one in Canada (without getting screwed shipping up from US)

Hymee, do you have any 'approved vendors' or shops in Syracuse that sell your product?

For that matter, anybody know of good shops in the Syracuse area?

Hymee , I can get you one .. and if you have a freind across the boader we can ship it there and save you some customs..
But lets get real your not going to may an arm and aleg.. I had to pay customs to get them here..

Anyway there instock and ready to go.. Email me with you full shipping and ill gt you a quote.

Here is our custom exhaust for autox etc.
It will be used on the street.
7LBS from flange back.
He is going to get me some pics of the stock mufflers cut open. I guess they are very restrictive looking.
This system should help with the hp/tq.
Dyno tests upcoming.
Call him if you want one.
I told him to use the stock pipe for part of the exhaust but he didn't have to. Cheaper that way.

the lightest one

So, is Flop going to have the first Hymee exhaust in Canada?

Cheers,
Hymee.

good ?

might as well add Abflug and Odula to make it more complete

Hello guys,

I need your help.

I am thinking to install a new exhausts. I have been looking for the Racing Beat lately but some say that it is not lounder (or not much lounder) than the stock exhaust. I am looking for a lounder sound than the stock but not too lound. Any recommendations? What about the Borla or Greddy? Are they lounder than the Racing Beat? Are they too lound? I don't want to sound like a civic, if you know what I mean ;)

Thanks guy!

How do I post a subliminal message? :D

Cheers,
Hymee, Hymee, Hymee.

So Hymee, are you saying yours is a bit louder than Racing Beat :rolleyes:

Yes. I have driven a racing beat equipped RX-8, so I was able to make a first hand comparison.

Cheers,
Hymee.

Anyone know where to get Mazdaspeed exhaust tips? ;)

Seriously though, what's the best exhaust system that's as quiet as the stock exhaust. I prefer quiet as possible. :)

well first of all it can't because you may not know this but it doesn't have a 4 cylinder, it has a rotary engine which sounds very different than a honda 4. i suggest you read your users manual and read the stickys and FAQs so you know what the rx8 is before you start modifying it :)

I have had my HKS exhaust installed for a week now and love it! The install was very easy, the removal of the old was painful.............

It has become a little louder over the week but not obnoxious. I can't really hear it unless I am accelerating hard. The sound is a bit deeper than the factory exhaust and it purrs.....or grumbles steadily......very solid.....

I can barely hear it inside the car, but my husband says you can definately hear it on the outside. He says that it doesn't sound noisy, but definately sounds enhanced...........
